Question

Keighlee has at most 60 minutes to finish her homework. She knows math will take 20 minutes. The rest of the time she will spend writing the final version of her science report. If it takes 8 minutes to write each page, which graph shows the number of pages she can write?

Answer 1

Keighlee has 60 minutes to finish. That's a fact.

What you want to do is subtract 20 from 60, because it is spent on math.
Next, you want to use 40, (the difference), and divide it by 8, to get 5 pages.

Hope this helps!

Answer 2

Total amount of time = 60 mins

Time take to do Math = 20 min

Time left after doing Math = 60 - 20 = 40 mins

Find number of pages:
1 page = 8 mins

40 ÷ 8 = 5
Answer: She can write 5 pages in 40 mins.
